Helen Pashgian was the only female artist associated with the Light and Space movement, a group of California minimalists that included Robert Irwin, Larry Bell and Peter Alexander. These artists were concerned with an issue central to art making: the perception of light and color in space. In pursuit of these elements, Pashgian helped to pioneer the use of industrial materials such as cast acrylic, resin and glass. The Pasadena-based artist became interested in cast polyester resin in the early 1960s and almost immediately began to use it to investigate how the ostensibly intangible character of color and light could be explored, controlled and even manipulated. Pashgianâ€™s reductive geometric sculpturesâ€”cast in clear resin, in a subtle hue, or in a rainbow of deep reds, greens and blues (not incidentally, the primary colors of light)â€”are able to focus solely on these fundamental principles of art because of their impeccable, and thereby undistracting, finish.
